Step 20: Use the last line under the body as a guide to draw the other hind leg the same way. This leg is stepping forward a bit, so make the hoof pointier on the left side.
Step 21: Use the remaining shapes as guides to draw the rest of the musk ox's body. Draw a series of quick, short strokes along the basic path of the guide to create the furry coat. At the top of the body, curve the path of the short strokes downward to create the hump. After that, simply follow the outer edges of the initial guides to create the shape of the body.
The strokes at the top should have a diagonal orientation, while closer to the bottom, they should be vertical. Make the strokes along the bottom longer to create a shaggier coat. The strokes should overlap the shape of the legs to emphasize the length of the musk ox's coat. Add a few short strokes to the left of the head as well to finish the shape of the body.
Step 22: For a cleaner look, erase as much as you can of the initial guide lines. Don't worry about erasing all of the guides. It's okay to leave some behind. Re-draw any final sketch lines you may have accidentally erased.
Final Step: Add some shading to your musk ox drawing for extra detail. Use a dark value all over the body to create the shaggy coat. As you shade, use strokes that go in the general direction of the hair. The strokes radiate outward around the head. Inside the head , they have a vertical orientation. Don't overlap the shape of the musk ox's horns as you add the dark value. The horns are light colored. Use a medium value for the forehead and for the muzzle.
Continue adding the coat around the fur and be careful so that you don't overlap the horns. If you do, just erase it. The strokes at the top should have a diagonal orientation, then gradually turn vertical toward the bottom. Adding the dark value can be very time-consuming, so be patient and take breaks. You can also use a black color pencil to make the coat darker and the process a bit faster. Musk ox coats are a bit lighter at the top, so use a lighter value here.
Don't push down too hard on your pencil because the graphite becomes shiny and you might tear the paper. Use a lighter value for the horns. Add some darker shading at the bottom to give them more volume. Use a lighter value for the musk ox's feet too but make the hooves dark. Add some shadows too. It's always a good idea to use reference as you draw. Don't forget to pause the video to draw at your own pace.
Add a cast shadow underneath. This helps ground the musk ox so it doesn't appear to be floating.
